   > @sarveshtamba from error, i can see that database can't be created due to timeout. Most likely, it is related to connection. You may have a try to start couchdb instance, and use `curl` to create database, and see whether there is similar issue. And then debugging the difference from the case in elixir.
   
   Hi @jiangphcn I tried to manually create databases as per `http://docs.couchdb.org/en/stable/setup/single-node.html`
   However the databases are already created(by the test cases in the test suites I suppose).
   ```
   root@pts00452-vm13:~# curl -X PUT root:eUMWzuP4@127.0.0.1:15984/_users
   {"error":"file_exists","reason":"The database could not be created, the file already exists."}
   root@pts00452-vm13:~# curl -X PUT root:eUMWzuP4@127.0.0.1:15984/_replicator
   {"error":"file_exists","reason":"The database could not be created, the file already exists."}
   root@pts00452-vm13:~# curl -X PUT root:eUMWzuP4@127.0.0.1:15984/_global_changes
   {"error":"file_exists","reason":"The database could not be created, the file already exists."}
   ```
   However new sample test DB could be created:-
   ```
   root@pts00452-vm13:~# curl -X PUT root:SfwUbHfo@127.0.0.1:15984/testcouchdb
   {"ok":true}
   ```
   I also tried to increase the timeout in `test/elixir/lib/couch/db_test.ex`, that did not help as well.
   ```
     def retry_until(condition, sleep \\ 100, timeout \\ 5000) do
       retry_until(condition, now(:ms), sleep, timeout)
     end
   ```
   
   Also the tests fail inconsistently, since in one of the runs only 2 failures were seen as below:-
   ```
     1) test replication by doc ids - remote-to-remote (ReplicationTest)
        test/replication_test.exs:228
